ADJUSTABLE PIPE-OPENING IN STOVES, 84.0.

SPECIFICATION forming part of Letters Patent No. 407,707, dated July 23,1889.

Application filed June 29, 1883. Serial No. 278,570. (No model.)

To aZZ whom it may concern:

Be it known that I, SAMUEL S. UTTER, 0 Brooklyn, in the county of Kingsand State of New York, have invented certain new and useful devices forAdjusting the Stove-Pipes of Stoves with the Stove-Pipe Openings inFire-Boards, Summer-Pieces, or other Similar Structures, of which thefollowing is a specf fication.

It is customary in constructing houses to prepare a fire-place openingbelow the mantel, and this fireplace opening is arranged to receive agrate when desired, which grate may be taken out when not in use and thefire-place opening closed by what is called a fire-board. This consists,generally, of aflat structure and is designed to close up the tire placeopening when the same is not required for the use of the grate. In thisclosingpiece or fire-board a suitable hole to receive a stove-pipe isprovided, so that a stove may be set up in the room when desired, eitherfor heating or cooking, and the smoke carried up the chimney-fluethrough this opening. As these openings in the fire-board and thecorresponding stove-pipe holes in the various stoves are of varyingheight, it is usually necessary to prepare and fit for every case, at aconsiderable expense, and often at loss of time, a stove-pipe elbow toconnect the opening in the closing-piece or summer-piece with thestove-pipe hole in the stove.

My invention has for its object improved devices to be attached tostoves, by the use of which a cheap direct-draft stove may readily beturned into a reversible-flue stove, and by which, also, within reasonable limits, the pipeopenings in the stove and in the closing devices,summer-pieces, fire-boards, or similar structures can be readilyadjusted relative to each other, so that they can be connected bystove-pipes without the necessity of having the elbows made specially tofit a particular position when the stove is to be put up.

In the drawings, Figure 1 is a back view of a stove having one form ofmy device adjusted thereon. Fig. 2 is a section through a portion ofFig. 1. Fig. 3 is a similar section having the back A reversed. Fig. 4is a view of the back A, showing some of the positions in which thestove-pipe collar may be adjusted. Fig. 5 is a view of a back A providedwith double openings for the adj ustable collar-piece.

Similar letters of reference indicate like parts in all the drawings.

In carrying out my invention I provide an auxiliary back A, of suitableshape to fit the back of stoves to which my invention is to be applied;This auxiliary back is so formed that when it is attached to the back ofa stove a suitable air-chamber will be formed between the back of thestove and the auxiliary back A, as clearly shown in the drawings. Aconvenient form of auxiliary back for this purpose is a trough-shapedcasting like the back A shown in the drawings, having suitable lips oredges to receive screws by which it may be secured to the stove. Such acasting can be very cheaply made.

On the vertical part of the auxiliary back A a suitable opening isprovided to receive a plate B, containing a pipe-collar and opening O.The plate 13 may be made of any suitable form which can be turned uponits center. The circular form admitting of a great scope of adjustment,will be found most convenient. The opening in the back A is of course tobe of a configuration corresponding to the shape of the plate 13. Theplate B is provided with suit-able devices to hold it in place in anydesired position. Convenient means of adjustment are those shown in thedrawings, in which the plate Bis provided with a fixed detent Ct anda mo*able detent or button b,which may be turned out of the way until theplate B is adjusted to the required position, when it is turned to holdagainst the inner side of the auxiliary back A, as is clearly shown inFigs. 2 and The holding devices for the plate B should be attached toand move with such plate, for by such arrangement the plate B can beadjusted in any desired position and the button I) will never be soplaced as to interfere with the collar 0.

As shown in the drawings, the adjustable plate B is provided with astove-pipe opening and suitable collar C, which is disposed thereineccentrically, so that by rotating the plate 13 in its opening in theauxiliary back A the collar C will beraised or lowered, as the case maybe.

The auxiliary back A is further so constructed as to be reversible inits position on the stove-that is, so that either end of it may be usedas the top part. This increases the scope of adjustment. Thus in Fig. 2the back A is shown with the collar-opening near the top of the stove,and in Fig. 3 the same back A is shown reversed,bringin g thecollar-opening near the bottom of the stove.

I may also provide two openings of equal size, as shown in Fig. 5, onein the upper and one in the lower part of the auxiliary back A. One ofthese openings is to receive the plate B, and for the other one a solidclosing-plate B is to be provided, the plates B and'B being of equalsize and interchangeable, so that either the upper or the lower openingin the auxiliary back A can be utilized for the pipeopening by simplychanging the plates B B. The plate B is to be provided with detent a andbutton 1), corresponding to those parts on the plate B.

It will be seen that by myinvention the flue of the stove may bereversed and the pipeopening readily adjusted to connect with the pipeopening in the summer pieces, fireboards, &c., either with or withoutthe use of an elbow, as the case may be.

Having thus described my invention, I do not claim, broadly, a collarpiece or opening in stoves adapted to be adjusted in Varying positions;but.

What I claim as new, and desire to secure by Letters Patent, is

1. A stove provided with an auxiliaryback A, of configuration adapted toform an airchamber on the back of the stove and provided with suitablesmoke-discharging opening,in combination with a plate B, adapted torotate in such opening and having a pipe-collar O and an opening thereindisposed on such plate eccentrically, such plate being further providedwith a lug a and button 1), substantially as described and shown.

2. As a new article of manufacture, a hollow auxiliary stove-back A,adapted to be attached to the back of a stove and to form an air-chamberthereon, such back provided with a suitable smoke-discharging opening,in combination with the pipe-adjusting device described, consisting of aplate B, adapted to rotate in such opening and havinga pipe-collar O andopening therein disposed on such I plate eccentrically, such plate beingfurther provided with a lug a and button I), substantially as describedand shown.

3. The hollow auxiliary stove-back A, adapted to be attached to the backof a stove and to form an air-chamber thereon, such back having twoopenings of equal size formed therein, in combination withinterchangeable plates B B, adapted to rotate in such openings, suchplates having suitable holding parts, as the lugs a and buttons Z), andone of such plates B having a pipe-opening and collar C disposed thereineccentrically, substantially as described and shown.
